After years of planning, Crater Lake Zipline is open for business, offering Oregon's longest tree canopy zipline, and the only tree-to-tree canopy zipline on U.S. Forest Service land, officials said Monday.

The 2 1/2 to 3-hour tour includes nine ziplines and two sky bridges suspended up to 90 feet in the trees in the Fremont-Winema National Forest, the Klamath County Chamber of Commerce said.

"Two of the course ziplines are more than a quarter-mile long each, and participants will zip over 1.5 miles of cable as they fly all nine ziplines. That's more than 8,200 feet of zipline cable suspended in the trees," explained Jenifer Roe, owner of Crater Lake Zipline.
